Dear Naveen,
it seems that you found a bug on our Java sample. Is it possible for you to describe exactly what you did to produce this error?
Cordially,

Dear customer,

Make sure that you call the function finalize when you initialize, another possibility could be that you are initializing more than once.

If you have more questions, let us know.
